  • Inkjet recording device and method for generating drive waveform signal
    Patent number: 8864263
    Abstract: An inkjet recording device is configured to cause a head control substrate to generate a first drive waveform signal and a second drive waveform signal. The first drive waveform signal is for applying, after 2 AL from finishing time of an ejection pulse P1 having a voltage V1 and a pulse width AL, a cancel pulse C1 having a voltage V3 (<V1) of the same polarity as the ejection pulse to a head. The second drive waveform signal is for applying, from finishing time of an ejection pulse P12 following an ejection pulse P11 each having a voltage V1 and a pulse width AL, a cancel pulse C11 having a voltage V2 (<V1) of the same polarity as the ejection pulses to the head.
